IMPROVEMENT IN GRAIN-DRILLS.

The Schedule ref-erred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, SILAS N. GALLUP, ofMacedon, county-of Wayne, State of New York, have invented certain new'and useful Improvements in Grain- Drills, of which the following is afull, clear, and exact description," reference being had to theaccompanying drawing making part of this specification,`and in which`Figure 1 is a perspective view taken from the under Side of the machine,and

Figure 2 is a vertical sectional view taken through the cogged wheels.

The invention relates to that class of drills or seeding-machines inwhich the hoes may be arranged in one row or in two rows, (that is,zigzag,) at the will of the operator.

The first part of the invention consists in a novel construction andarrangement of the devices for aetuating the bars to which the drag-barsof the hoes are attached, the object of my improvement being three-fold:first, to dispense with one set lof gears fo r operating the bars;4second, to furnish a central support for said bars against the backwardstrain pro` duced by the hoes; and third, to make them mutuallylsupport'each other.

'lhe second part ot' the invention consists in mounting the bars in anadjustable frame, by means of which construction the hoes can be movedeither forward or backward out of the way when it is desired to sow thegrain broadcast. l

The nature of these improvements will be fully understood from thefollowing description.

In vthe drawing- A A represent the longitudinal or side pieces of theframe, uponwhich the hopper and seeding devices of the drill aremounted.

B is the forward transverse girt, to which the tongue is attached. y

C is the tongue, which may be secured to transverse girt B in any usualor desired manner.

D is a sill or base, which, with the end-blocks E, forms a frame-workupon which are snpportedthe bars F G.

Bars F G are mounted upon pivots which turn in suitable bearings inblocks E, (shown in dotted lines centers are coincident with the centersof the pivots e, so that if the wheels are rotated 4in either directionthey will remain in mesh with each other, -the arrangement of theseparts being fully shown in g. 2.

K is a strap or shell surrounding the two wheels I I', substantially asshown in fig. l, and tit-ting them closely. 7

This strap serves a double purpose: First, it serves g to keep the twocogged wheels I I'always in mesh, as without'it (the strap) the backwardstrain-upon the rear bar Gr would at times, from the strain of the hoes,withdraw it (cog-wheel I) from the `wheel.1nounted upon bar F. The strapnot only keeps the wheels in mesh, but, secondly, it makes the irst barF assist in supporting the rear one, G, against any unusual strain whichmay be thrown upon it. f

vThe strap K is rigidly secured to base or sill D, and'i'sthus made tosupport both bars centrally, independently of one supporting the other,as above described. v

Lis a rod or link attached to one of the *cogged wheels, and so locatedas to be within convenient reach of the attendant.

The frame-work DE E is mounted upon the tongue and secured thereto bybolts in such manner that it can be moved backward or forward, as thecase may be, in orde/r to move the hoes from immediately below thedistrihuters when the machine is used for sowing broadcast. l

In using my devices the wheels I I' are operated by the link L to movethe free edges of bars F G in opposite directions, carrying with themthe drag-bars, thus arranging the hoes in one or more rows, as may" berequired.v

' The link L should be locked in position by some of the well-knowndevices, which it is not necessary to describe here. ,Y

In practice the cogged wheels should be cogged upon such portions oi'their peripheries as shallbe engaged with each other, thus leaving suchportions as bear upon the strap K smooth.

.Having now described my invention,

What I claim as new, and desire to secure by Letters Patent, is a l. lhecombination cf cogged wheels I I and strap K with the oscillating bars FG, substantially as set forth 2. In combination with the bars F G anddrag-bar H, the movable frame D E E, substantially as set forth.
